Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”), methods of fabricating PDCs, and applications for such PDCs. In an embodiment, a method includes providing an at least partially leached polycrystalline diamond (“PCD”) body. A residual amount of acid may remain in and/or on the at least partially leached PCD body. The method further includes removing and/or neutralizing at least some of the residual amount of acid from the at least partially leached PCD body and/or a substrate to which the at least partially leached PCD body is attached.

Abstract: In an embodiment, a polycrystalline diamond table includes a plurality of bonded diamond grains and a plurality of interstitial regions defined by the plurality of bonded diamond grains. The polycrystalline diamond table may be at least partially leached such that at least a portion of at least one interstitial constituent has been removed from at least a portion of the plurality of interstitial regions by exposure to a leaching agent. The leaching agent may include a mixture having a ratio of weight % hydrofluoric acid to weight % nitric acid of about 1.0 to about 2.4, and water in a concentration of about 50 weight % to about 85 weight %. Various other materials, articles, and methods are also disclosed.

Abstract: In an embodiment, a method of fabricating a leached polycrystalline diamond (“PCD”) body is disclosed. The PCD body includes bonded diamond grains defining interstitial regions at least a portion of which include at least one interstitial constituent disposed therein. The method includes leaching the PCD body with a leaching agent to remove at least a portion of the at least one interstitial constituent therefrom. The leaching agent includes a mixture having hydrofluoric acid in a first concentration of about 10 weight % to about 50 weight %, nitric acid in a second concentration of about 5 weight % to about 25 weight %, and water in a third concentration of about 25 weight % to about 85 weight %. Further embodiments relate to different leaching methods and different leaching agent compositions.
